Abstract:
A piston for an internal combustion engine has a piston head and a piston skirt. The piston head has a circumferential ring belt and a circumferential cooling channel. The piston skirt has a working surface assigned to its major thrust side and to its minor thrust side. A bore that proceeds from the cooling channel is provided, which ends in the working surface assigned to the major thrust side, and is disposed at an incline, in such a manner that the bore exit encloses an acute angle (α) with the center axis (M) of the piston. An opening is formed in the working surface, and a deflection surface inclined relative to the working surface is provided between the bore and the bore exit. The working surface assigned to the major thrust side has a depression which forms at least one oil capture region above the opening.
